Will the new hole in the rear arms be beneficial for mm on outdoor loose/ rough track conditions??

So is it really worth dremelling the chassis guards to run the battery sideways?

I can tell you my own personal opinion next Friday when I get it back on the track. But I can say that when I tried the inline setup on my B5M I wasn't a fan.

Can somebody help me with this. I got an RB6 from the for sale section on this forum during the winter and I just got around to setting it up. I got all the electronics set up and I never checked the spur until I took off the cover to install the motor and I saw this its a 66T spur with no markings whatsoever with a slipper I have never seen before I don't know who makes it. I guess the person I purchased this from ran 17.5T class since the spur is so small. Anyway can somebody tell me who makes this spur and can I get a larger size maybe a 72T or 82T since I will be running an 8.5T motor. The biggest pinion I have is a 28T and that still won't get close to this spur.

Looks just like the Schelle Racing Nova slipper ( http://www.amain.com/rc-cars/schelle...A25BoCtiTw_wcB )I just pulled out of mine. I could not get the thing set up and will be going back to stock.

I love my nova slipper. I can't imagine what sort of issue you were having.

You'll need to pick up a bigger spur gear if you're going to run an 8.5T motor. Order a new one from Schelle. The Novas are great. Amain also sells them.

Not sure as I am a bit of a novice, especially being I never dealt with a slipper. The car is WAY under powered and it has a Orion R10Pro ESC and a Reedy 7.5! Under any traction it seems to just slip out. I had a few locals try and adjust the slipper with no luck. Maybe it is not the slipper?

could also be your diff. if the person was running a stock motor in it the diff is probably pretty loose.

hmmmm....

First make sure the slipper is assembled properly. It can be a little tricky. Make sure all the washers and pads are in the proper places. While doing this have an experienced racer check your pads. You don't want them to look glazed. If they are a quick lap around some high grit sand paper will clean them up. Also check for build up the metal discs.

Next have an experienced racer check and adjust your diff. If it needs to be tightened you may want to run it in a couple of times (hold one wheel and apply 1/4 throttle, allowing the other wheel to spin freely for approximately 20 seconds) and check it again.

Finally do a slipper test on the bench. Place your buggy pointing away from you. While holding your radio in your throttle hand; hold one rear wheel firmly with your free hand and then firmly press down on the other rear wheel with base of the radio. Now give the throttle a firm blip. Don't hold it just a quick blip of full throttle. Note how high or if the front wheels lift off the ground. Also note any sounds that may result. A high pitched squeak is the slipper. A midrange "bark" is the diff. Another way to know if it is the diff or the slipper is to watch the reaction of racers near-by. They won't react to a slipper chirp, but a diff bark will send them into convulsions. Barking the diff is bad, one small bark won't kill it, but more than a couple will ruin a brand new diff. You want to see the wheels lift off the table by about 2" to start. Not enough lift and you'll find it difficult to accelerate rapidly, too much and the car will become difficult to drive.

Above all, don't be afraid to ask for help. I have come across very few racers who won't help if asked, but even less racers have the ability to tell that you are having difficulty with out you asking.
